Burg Kreuzenstein is a castle near Leobendorf in Lower Austria, Austria. Burg Kreuzenstein is 265 metres (869 ft) above sea level. It was constructed on the remains of an early medieval castle that had fallen into disrepair and was then demolished during the Thirty Years' War. Intended to be a family vault for the family, it was rebuilt in the 19th century by Count Nepomuk Wilczek with money from the family's large Silesian coal mines. Kreuzenstein is interesting in that it was constructed out of sections of medieval structures purchased by the family from all over Europe to form an authentic-looking castle. Thus, the castle can be considered both a 'neo-' and 'original' medieval structure.The castle is sometimes used as a location for films.
